Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical induction devices require manual access through a manhole for connecting electrical conductors, such as bushings or surge arresters, to transformers, which is inconvenient and limits flexibility in positioning and inclination tolerances.
Innovation Solution
A contact arrangement within the housing of the electrical induction device featuring a receiver contact and a resilient suspension arrangement that allows automatic adjustment in the xy-plane, enabling the electrical conductor to connect without manual adjustment, using a plug-in mechanism that accommodates varying positions and inclinations of the conductor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual connection through a manhole is used, then the electrical conductor can be connected, but the operation is inconvenient and requires physical access to the housing
Solution Approach 1:
The contact arrangement enables self-aligning connection through the resilient suspension arrangement that automatically adjusts the receiver contact position to match the electrical conductor position, eliminating the need for manual adjustment through a manhole
Solution Approach 2:
The receiver contact is made resiliently movable in the xy-plane through the suspension arrangement, allowing dynamic adaptation to position and inclination variations of the electrical conductor during connection
2Reliability
If fixed position connection is used, then the connection is stable, but the tolerance for position and inclination of the conductor is limited
Solution Approach 1:
The receiver contact transitions from a fixed position to a dynamically adjustable position through the resilient suspension arrangement, enabling adaptation to various conductor positions and inclinations while maintaining reliable electrical contact
Solution Approach 2:
The position parameters of the receiver contact are made variable through the resilient suspension mechanism, allowing the contact to shift within the xy-plane to accommodate position and inclination tolerances of the electrical conductor
